I am using Hash#to_xml in my Sinatra application. It did work till I moved to actviesupport 3.0.0
Is there a difference in usage of activesupport in 3.0.0?
For example this works fine
gem 'activesupport', '2.3.5'
require 'active_support'
{}.to_xml
and
gem 'activesupport', '3.0.0'
require 'active_support'
{}.to_xml
generates: NoMethodError: undefined method `to_xml' for {}:Hash
